To all whom it may concern:

.Be it known that I, 'Willman Voss, residing at Wilmington, Delaware, and being a citizen of the United States, have invented certain new and useful Improvements in Trucks, of which the bfollowing is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawfngs, which illustrate the 'preferred form of the invention, though itis Ato be under-iy stood that the invention isnot limited to the exact details of construction shown and described, as it is obvious that various modi-VA persons skilled of the present invention, a fragment of t-he bolster being broken away for disclosing a' portion ofthe spring plank. Fig. 2isa viewf 'of the same in one-halt` elevation and o1ie- `half vertical central section, parts being seeni in elevation in the sectional half. Fig. 3 is an end elevation thereof with a fragment; broken away and showing arts in section., Fig. 4 is a` transverse centra section, a portion of the bolster being seen in elevation; and a fragment being broken away and other parts bein seen inl elevation. Fig. 5 is kan enlarged etail view of one of thevchafing, plates or dampers, a fragment of the cross; tie bar, bolster' and wheel piece being seenK iiiplan. Fig. 6 is a transverse,vertical sec-. tion taken on the plane indicated by line 6, 6, of Fig. 5, 'and lookingin the directiony ',ott'the arrow. Fig. is a longitudinal,'vcrtical 'section/taken' on the plane indicated byline 7, 7, o't' Fig. 5, looking in the direc-1 tion-of the arrow. Fig. 8 is a transverse, vertical `fragmental section taken on the plane indicated by line 8, 8, of Fig. 5. Referring to the drawingby numerals,l 10, 10, indicate ordinary axles for the usual4 wheels 11, the boxes 12 thereof being en-l gaged by pedestals 13 and equalizerbars 14 in the usual manner. Iedestals 18 arey riveted orotherwise suitably -secured to and carried by the wheel pieces 15, 15, and saidwheel pieces are mounted upon springs 16, 16, sustained by the equalizer bars 'l-t each spring 16being held in position at its lower end by the ordinary seat l17,"and at its .pp'er .nml bv ca'p 18, hereinafter mentioned. Each,

wheel piece, as best seen in Fig. 6, is formed of an H-section, each ot' the vertical flanges 15 of which is ot' a width equal or substan-VA tially equal to the width oi' the connecting or horizontal vweb 15.

Connecting the respective ends of the wheel pieces 15 and completing th'e main portion of the truck trame are the end pieces 1l), 1f), cach of which is connected at its ends with the corresponding ends of the wheel pieces, in the manner best seen in Figs. 1 and 3.A A corner web plate 20 is fixed to each end ot' each piece 1S), and extends a suitable distance longitudinally of the re- Spectlve wheel piece and has a right-angular outer edge, corresponding to the angular relation of theend piece andv wheel piece, the web plate lying between the horizontal flange et the respective end piece 1S) and the horizontal web of the wheel piece 15. As clearly indicated in Fig. 3, the lower half of the inner flange of the respective wheel piece is Cut away :tor accommodating the web plate 20, the end ot' the respective end piece 19 extending to the outer vertical flange of the wheel )ieee-as indicated in full lines in Fig.

3 and otted lines in F ig. 1L Each web plate 90 is secured by`rivets 2l to' the horizontal flange of end piece 19, rivets Q2, 22, extending through the horizontal web of wheel piece 15, through web 9.0, and through the horizontal [lange of end piece 19 for connecting the parts together. The web plate 9.0 is further riveted to the horizontal web of wheel piece l5, as at Q3, 23. The web plate 20 .may be in the form of an angle but is preferably provided with a bracing fil let Q4.

At cach side ot' the truck frame, a tension strap 25 is arranged, thc salue being bolted or otherwise suitably secured at its ends to the respective ends ot' the corresponding. vwheel piece l5, and extending beneath and connecting the pcdcstals 13 of the respective side of the frame. each strap Q5 being preferably bolted or otherwise suitably attached to each oit such pcdestals. The straps Q5 are connected by cross lios E26, 26.

spaced apart, longitlulinally of the' trucks' frame, and extending transversely of said frame are transoms Q7, 27, each having eachl oi its ends bent or turned upwardly at substantially right angles, as indicated at 2T', und clcarliv soon in Fig. hll, the turned portion 27' tcruiizuitiug in a T-head 28, riveted with vsaid bearing plate and filler Y `otherwise suitably iixed to the bolster, and

,or otherwise 'suitably secured, as at 29, to -the horizontal web of the Arespective Wheel pin 32 sustaining swinging hanger 33, 'the hangers being thus arranged in pairs atlthe opposite ends of the transoms, and each pair of hangers carrying a cross bar 34. Mount ed upon the cross bars 34," 35 consisting preferably oi a channel plate having at each end a filler `block 36 engaged by the. respective cross bar 34. Blocks 36 are preferably of Wood. Each of the cross bars may be bolted to the spring plank 35, as indicated at 37. It is to be noted that the filler blocks 36 may be formed of any thickness desired, thicknesses may be used as desired for altering the elevation of the spring plank', and thereby altering the elevation of the superposed structure, and thus adjusting the relative position of the draft rigging.

Mounted at each end of the spring plank 35 and preferably immediately above cross=v bar 34 is an elliptical spring 38', which may be retained in position in any ordinary manner. YStrips 39, 39, extend across and are riveted to plank at each end thereof, each of the ends of the strips 39 being upturned for engaging the spring, and the central clips 40 ot' the spring being disposed between the strips 39. A similar pair oit strips t1 engages the upper part of the springend is carried at each end of the truck bolster 4t2.

As best seen in Figs. 2 and 4l, bolster 2 consists of four channels 43, arranged parallel to each other and extending trans versely of the truck frame and provided an upper cover plate le and a lower cover lplate 45, each of the cover plates being suitably riveted or otherwise suitably attached to the lianges of channels 43. The channels i3-are spaced apart, and the flanges ot' the set of channel beams at one side of the .median line of the bolster are disposed out Wardly in one direction, and the tlanges of the other set of channel beams at the other side are disposed outwardly in the other direction. Arrangedcentrally of and resting upon bolster i-2, iS a filler plate iti upon which is mounted center bearing plate a?, being bolted or plate if? being adapted to be engaged by the conter bearing of the body bolster 48. 0bviously, the Eller plate @t6 may bemade ot greater or less thickness und thus the elevation of the center bearing be varied 'for tering` the elevation of the couplers or draft rigging, v

[is thus constructed it is obvious that the bolster 42-inay swing 'vertically and trans Vorsely ot' the truck in the absorbing ot is a spring plankand blocks of differentr cyanea i shocks, and it is Well known that-the movement oi: the bolster when unrestricted is liable to become violen'tror at least menacin', and, in order to avoid this diliculty, varions forms of more or less eilicient and more or less expensive dampers have been heretofore proposed, and the present invention involves simple and .relatively cheap and citiw cient means to this end. Preferably formed integralavith each cap 18 is a plate 49 which may be a steel casting or other suitable Inaterial. 'As clearly seen in Fig. 7, that portion of plate t9 extending beneath the respective WheelV piece 15, is provided With an upstanding tulilular extension or sleeve 50, a similar extension or sleeve bein formed on the upper surface of cap 18, said cap being part of plate e9. That portion of said plate which under-laps the respective Wheel piece 15 rests against the lower edges of the vertical iangeszoi" the wheel piece, and sleeves 50 serve as fillers. Said underlapping portion of plate i9 strengthened by ribs 51., 51,

extending upwardly between the vertical tlanges of the wheel piece. A rivet or other suitable securing .means is passed through each sleeve 50, and through the underlapping portion of plate Litl, and through the horizontal web of the lei-section constituting the wheel piece. Thus each plate fil-9 is firmly and rigidly held in position and sustained by the respective contiguous wheel. piece, and the plate extends inwardly from the wheel piece and tapers to a plate 53, backed by suitable Webs 49 formed iitegal with plate Lit). Plate 53 is formell with a vertical, flat .tace presented toward und disposed conn tiguous to the bolster lhe respective end of the corresponding outer` channel beam i3 of the bolster is provided with a filler block 5ft, faced by u preferably spring steel Wearing plate disposed to contact with a siniila r plate 56 fined to the plate 53. The plate :3G is riveted or otherwise suitably secured to plate 53, and plate is secured in position by rivets, or other suitable attachl ing ineana'", extending through the filler plate 54 and through the vertical iia'nge of the respective channel beam 43. Thus, as each end of the bolster is engaged by a friction plate at each side, the vibration of the bolster will be damped and maintained within limits, and at the same time the chang plates will be liable to but a minimum amount oi weer, and when. worn may be readily replaced. Of course the renewal of the chaiing plates simply involves the supplying oit' new plates and A56.

A cross-tic bar 57 is arranged at each side of the bolster and spaced outwardly troni the respective transom 27, and the opposite ends of cach bar 57 nre riveted or otherwise suitably secured, as at 58., 5S, to the respective plate 49. Each bar 57 is preferably of angle section. Each barr', :it each end, carries a bracket 59 in the form of an angle adapted to ht against the flat outer ,t'aee of the vertical web of 'oar 5T and against the under .tlat l'aec of the resieieetive plate et),

the corner of bracket (if) being 'formed with a fold, providing bearing (it), in which is mounted the brake shoe hanger ol. .llaeh bracket 5.() is secured in place by boltsor other suitable attaching means, G2 and G3, extending respectively through the bracket and vertical flange of the bar 57, and through the bracket plato 49 and horizontal web of bar 57. Movably sustained by hangers (Sl, are the brake shoes (3ft, which a rc connected to and adapted to be operated by the trussed brake beams G5. Eachv beam (35 has its tension member sustained in the usual manner by a bolt (3G and a spring 67, the latter being suitably attached to bar 57. A pair of brake release springs (38'is'tixed to each bar `5T and engages the respective brake beam for retaining the shoes in the normal, released condition. A brake lever G9 is pivotally connected/with the strut of each of brake beams G5, and the lower ends of the said levers are connected by the usual link 70, one of the levers 69 being designed tobe engaged by the brake draft appliance, and the other being adapted to have its free endadjustably seciu'ed to a longitudinally disposed tie beam 71, fixed to and extendii'ig :trom one of the bars 5T and connected lwith one of the end pieces 19. The other bar 57 is engaged similarly by a similar tie bar 72. Hanger brackets 73, 7i, depend :from each ot' the bars Tand surround the respective brake beams as safety devices for avoiding damage when the regular brake beam support becomes broken or ineil'ectual.
